Product Description

4.0KW Automation Direct VFD Variable Frequency Drive For 3 Phase Motor

DC Braking Frequency 0.00Hz To Maximum Three Phase VFD Automatic Torque Boost


The CM540 series is a high torque type vector inverter. Its motor control performance increases obviously. The inverter can implement the control of asynchronous motor and permanent magnet synchronous motor (PMSM), supports multi-kind PG and IO cards(including CAN COMMUNICATION).The function is more powerful. It is used to drive various automation production equipment involving textile, paper-making, machine tool, packing, food, elevator, crane, pertrolum machinery, fan, pump etc.










                                             Basic Function
Maximum frequency Vector control: 0~600Hz | V/F control: 0~3200Hz
Carrier frequency 0.8kHz~12kHz. The carrier frequency automatically adjusted based on the load features.
Input frequency resolution

Digital setting: 0.01Hz

Analog setting: Maximum frequency ×0.025%

Control mode Open-loop vector control (SVC), Closed-loop vector control (FVC), VF control.
Startup torque G type: 0.25Hz/150% (SVC), 0Hz/180%(FVC), P type: 0.5Hz/100%
Speed range 1:200(SVC), 1:1000(FVC)
Speed stability accuracy ±0.5%(SVC), ±0.02%(FVC)
Torque control precision ±5%(SVC)(above 10Hz), ±3%(FVC)
Overload capacity

G type: 150% rated current 60s. 180% rated current 3s.

P type: 120% rated current 60s. 150% rated current 3s.

Torque boost Automatic torque boost. Manual torque boost 0.1%~30.0%
V/F curve Five modes: Straight-line, Multi-points, Square V/F, V/F separation, V/F Semi-separation
V/F Separation Two modes: complete separation, semi-separation
Ramp mode

Straight-line ramp and S-curve ramp.

Four kinds of acceleration/deceleration time with the range of 0.0–6500.0s

DC injection braking

DC braking frequency: 0.00Hz~maximum, braking time: 0.0s~36.0s.

Braking action current value:0.0%~100.0%

Jog control

Jog frequency: 0.00Hz~50.00Hz

Jog acceleration and deceleration tome:0.0s~6500.0s

Simple PLC, multistage speed operation It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.
Built-in PID It can keep constant output voltage automatically when the mains voltage changes.
Automatic voltage regulation(AVR) Automatically maintain a constant output voltage when grid voltage changes.
Over voltage/Over current loss of speed control Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage
Rapid current limit Minimizing over-current fault and protect the normal operation of converter.
Torque limit and control "Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.


Description of Indicators:

RUN:ON indicates that the AC drive is in the running state, and OFF indicates that the AC drive is in the stop state.

LOCAL/REMOT: It indicates whether the AC drive is operated by means of operation panel, terminals or communication.,off indicates operation panel control, on indicates terminal control. Blinking indicates communication control.

FWD/REV: On indicates reverse rotation.

TUNE/TC: When the indicator is ON, it indicates torque control mode. When the indicator is blinking slowly, it indicates the auto-tuning state. When the indicator is blinking quickly, it indicates the fault state.
